To all whom it may concern:

Be it known that I, JOSEPH BOLTON I40- MAX, a subject of the King of Great Britain,

' residing at BirchLea, Furness Vale, near Stockport, in the county of Derby, England, have invented new and useful Improvements in Finishing or Ilustring Textile Fabrics, of which the following is a specification.

My invention relates to an improved and contlnuous process and apparatus for finishing or lustring textile fabrics such as sateens, batistes and the like, but it is applicable to various other classes of fabrics whether mercerized or unmercerized.

In carrying my invention into effect I pass the fabric through a heavy Schreiner calendering machine on which I use a much heavier pressure, say from two to three times as great as for ordinary Schreinering, and I also employ a greater heat to bring the engraved roller to a blue heat or to as great a heat as the cloth will stand without injury.

Immediately the fabric leaves the nip of the Schreiner calende-ring rollers and while still heated I pass it under tension in the same machine over'or under a rotating roller mounted in a box or receptacle and partially immersed in a finishing li uor contained therein by which a film of t e liquor 1s applied to one side or both sides .of the heated fabric.

poses of my invention.

The accompanying drawing shows in elevation a known form of S'chrei'ner calendering machine which I em loy for the purhis machine consists of a frame or pedestal a carrying the pair of Schreinering cale'ndering rollers of which the upper roller b is engraved and brought to a blue heat or as great a heat as the cloth will stand without injury and the lower roller 0 is carried on a ram diet a hydraulic press inthe usual way. The fabric e to be treated is led from the batch roller 6 through the usual tensionin device f between the nip of the rollers and c where it is subjected to a pressure from two to three times as great as that employed for ordinary Schreinering. Immediately after leaving the nip of the rollers b and c a film of finishingliquor contained in a trough g and maintained at or about boiling point is applied to the underside of the heated fabric -(either merce'rized or unmercerized) boiling finishing liquor while retaining the jacent to and parallel wit e by means of a finishing roller h and the fabric eis then wound on an ordinary batch roller if, which may be rotated by any suitable means, such for instance as a belt and pulley from any convenient source of power. I

.The fabric is left to stand batched in its underside but it will be readily understood that if required the fabric may be guided under the roller h and the finishing liquor applied to both sides. The finishing liquor is composed preferably of a boiling solution of alizarin oil say a 10 to 20 per cent. solution of alizarin oil.

By my improved process I obtain a fabric on which the color is more intensified and with a sheen or luster which will resist rain and weather without spotting and will stand washing in hot'or cold water without any deterioration after drying.

What Iclaim as m invention and desire to secure by Letters atent of the Unlted States is 1. The process of finishing textile fabrics which consists in passing the same between a plurality of rollers under high pressure and heat and while hot applying thereto a fabric under tension, and winding said fabric into a roll while in hot condition.

2. The process of finishing textile fabrics which consists in passing the same between a lu'ralityof rollers under high pressure and heat and while hot applying thereto a boiling solution of alizarin oil while retaining the fabric under tension, and winding said fabric into a roll while in hot condition. I

3. In a machine for finishing textile fabrics, 10

the combination with a calendering machine having a pair ofcalendering rollers, a pair of batch rollers one at each side of said calender, ing rollers, and tensioningmeans, of a receptacle for a boiling finishin liquor located adsaid calendering rollers, and a finishing roller disposed longitudinally partly Within said receptacle and having a portion of its circumference in the .path of the fabric when passing from the ply it to the fabric immediately as the latter emerges from the calendering rollers and while in hot condition.

In testimony whereof I have signed my name to this specification.
